Shopkeepers passed a sting operation that was carried out to catch them selling cigarettes or synthetic cannabis to minors.
Last week, two teenage volunteers and Wairarapa DHB's smokefree enforcement officer, Nicky Poona, visited 13 retailers from Featherston to Masterton to see if they would pass the test.
Ms Poona was pleased to find none of the retailers sold to the teenagers and they were asked for ID each time.
"This was a controlled purchase operation (CPO) with the three of us visiting mainly dairies."
"I'm glad to say that we had no sales of cigarettes or synthetic cannabis," she said.
